Substitute a L90ls electrovalve with resistances:

Dingoma 1 year ago updated by Gustav Widén (System support) 1 year ago 3

Hello, I want to know if is possible to substitute a L90ls electrovalve with a resistence to check an expansion module.
I want to make a  bank to conect a master or a slave module (XP2, XA2, MC43...) and check outputs of the module.
As the electrovalve has 21-23 ohms, I've used a 20 and 30 ohms resistence, but  "open load" error appears with both options.
Is there any way to check the outputs with a test bank?


4-20mA , 0-5,0-10 VDC industrial command signals

Steve Liljestrand 2 years ago updated by Theo 11 months ago 4

The MC4x now has Current loop inputs (4-20 mA) but no 4-20 mA Output. 

Does Parker IQAN ever plan to offer a module (ICP Compatible) with Industrial output command signals Such as 4-20mA , 0-5VDC and 0-10 VDC?

I work with some Hybrid applications that integrate Industrial PLC's with IQAN Mobile controllers.

We are often struggling with signal integration between the two platforms. I know there are CAN to Analog solutions but they cost money and take time to integrate.


Software download via USB

It would be super helpful to have a USB port on new master modules that would allow end users to plug in and download new software that we could send them, instead of making them purchase IQAN Run. Just an idea, I'm sure others agree that some sort of alternative way to allow end-users or dealers to load program updates would be very helpful. (if there is a way to do this without any additional hardware please let me know)


diodes on coils

Theleo De Bruyn 9 months ago updated by Gustav Widén (System support) 8 months ago 1

Hi there!

we are using prop valves for an application. and we use a cout (current out) to control them. but over the 2 pins of the coil there is a LED with a resistor. and in the instruction of our module (MC43) they say: Do not instal diodes over the coils.

so i was wondering: is a LED a Diode in this application? Do i need to remove the LED?

Thanks for helping!

I have an old faulty IQAN-DG here for repair.

Can someone please send me a diagram of the rear CI, CAN1 and CAN2 connector pinouts.

Thank you


9V valves

Theleo De Bruyn 1 year ago updated by Gustav Widén (System support) 1 year ago 0

Dear reader,

I need for an aplication a proportional  9 Volt output. is this possible with the system running on 24 Volts? Because if i would use a COUT the voltage would be 24 V.

Is it maby possible to use a PWM output? 

if so, how do i use PWM?

Another option is to run the system on 9V, is this stable to use?


over voltage possible?

Theleo De Bruyn 1 year ago updated by Gustav Widén (System support) 1 year ago 3

Dear reader

we need for an aplication 4 Voltage inputs on one of the MC4x serie, those voltage inputs aren't a problem but we need to have voltage inputs for 0-7 Volts. is it possible to connect those sesors on the voltage in for 0-5 Volts ,0-5 Volts will do the job in our program. this 7 Volts on the input isn't continuous, these are just peaks.

Thanks for the help!


IQAN-DG Display failure

David Kiu 1 year ago updated by Søren Højvang Pedersen 3 months ago 3

Hello admins  & all,

I bounced into this forum while searching for information pertaining to IQAN-DG instrument.

My problem is that the display is distorted or rather damaged. On the printed circuit board, it stateds DMF5001NY-LY  Org_DMF5001NY-LY.jpg . I managed to acquired a new display unit DMF5001NY-LY-ATE-BBN . After installing, this display unit seems not compatible! The resolution of the text seems

weird, enlarged, cut-off and shifted to the right side Text_res1.jpg Text_res2.jpg.

As i am lack of technical information regarding the screen resolution, i am lost here. I assume this is a resolution problem with the new display unit.

Any information, help or solution to this problem is greatly appreciated.

Any information on this? I just saw it in the release notes for, I added it to my project but I can't figure out how to do anything with it right now.. but information on the hardware would be nice.


MC2 cout output PWM,

flipper80 1 year ago updated by Tim Reen 11 months ago 13


Want to drive a D1FB Parker proportional valve withMC2 controler... Would like to know difference between PWM and so called COUT output (also said current mode and closed loop) both have to drive 24v coil. It seems they are both Pwm? BTW cannot find recommanded valve dither frequency.

Thanks for your help
